TO ALL WHOM IT MAY GONOERN:

Be it known that I, WILLIAM C. Beuren, of Huntingdon, in the count-y ofHuntingdon, and State ot' lPenn-` i sylvania, have invented a new anduseful Improvement in Brick Machine; and do hercbydccdare that thefoil-giving is a full, clear, and exact description thereof, which willcnablelothers skilled in the ari to malte` and use the same, referencebeing had to the accompanying drawings, forming part ofthisspcciiication, in Which-v- Figure l is a horizontal section of myimproved machine, taken through the line :c 1v, iig. Figure 2 is avertical cross-section ofthe same, taken throughthe line y y, 5g. `4.

Figure 3 is aside view of the saine, the wheel being removed to show thcconstruction. Figure 4 is averticellongitudinal section of the same,taken through the line e z, tig. 2. Similar letters of referenceindica-te like parts.

. l 'My invention consists in an improved brick machine, so constructedand arranged-as hereinafter more fully described, that the empty mould-smay be raised automatically from the lower to the` upper part of themachine L" While it is being drawn to the pit Where the clay is preparedfor moulding; and so that after thc;ternpc1jcd clay has been put intothe hopper, While-the machine is being drawn from the pit to the doornhcre the moulded brick are (Med, the said empty moulds mayautomatically be lowered, passed beneath the hopper, hlled, and passedout upon shelves at the other end of the machine, ready for removal tothe dryingl loor. i

A and B are the 'wheels upon which the. machine is supported, and by themovements of which it is Qpe'r. ated. Querer more small wheels, as (l,may be placed under the ends of the machine to hold vit in an erectposition While being loaded and unloaded. The wheel revolves looselyupon the axle or shaftD, but` the Wheel B `is securely attached to saidshaft, and carries it with it as it revolves. The shaftD revolves inbearl ings, E, attached to the 'sides of the frame or box, F, as shownin iig. 3. Gr are smallwheels attached to` the i 'shaft D,upon theoutside of and close to the box or frame F, as' shown in figs. 1 and 2.p Each of the Wheels G is lmised with one cog, as shown in iig. 8, forthe purpose of raising and lowering the slides H, as hereinafterdescribed. are cog-wheels attached tothe shaft D within the sides of theframe or box F, as shown in figs. l.

yf .and vg, for the purpose of transferring the moulds, J, from one endof the vbox F tofthe other, as hereinafter i 4, and has six shelves, Kand L, formed in each end, as shown in iig. 4, foi' the reception ofthemoulds J'. The

"" l ends of the shelves K L are securely attached` to the slides H, andthey are so arrang@ Vthat when the said i described. The box or frame Fis a little longer than three times the breadth of theV moulds J, asshown in iig.

5 Elides H are raised to their full height the lowest shelil on eachside shallbcin a lineu'vith the stationary shelf, i@ M. The shelf` M issecurely attached to the frameof the machine, and has holes' throughitin which are placed pipes, N, through which` the surplus clay' thatescapes-.from themoulds J mayhem' tothe mould O, upon the shelf P. The'mould O remains permanently upon the shelf P, exceptwhen drawn-outbyhand` by means o f the handle of, to be emptied, The tivo slides, H,on each side of the machine, and pc, ,yhhv the shelves are attached,are'connected together at their upper ends by the arches L, and the twoarches are connected to each other at their centres by the shaft R, fromwhich the presser S is suspended by means of tlle'rigid uns T7 `When theslides H have been raised to their full height, the presser S may beswung to'onejsiderover the end of the box or frame F, where it is heldout of the way by the spring-catch U, whileithe hopper V, in `which itWorks,`i`s being filled with clay, The lower i edge of that side of thehopper- V, at which the moulds .l' enter, terminates iu an apron, W,slightly inclined inrrard, which gives to allow` the said moulds toenter, and which, when thev clay is acted upon by the presser is forceddown close uponA the side of` `said mould, t0, prevent the escape .ofthe clay over its sides. Upon the lower edge of theothcr side ofthehopper V, is formed, orto it is attached,

a knife or scraper, X, siightlyinelined inward, which cuts or scrapes.the surplus clay from `the top of `the moulds as they are being drawnout from beneath thc ,hopper V, and forced upon thc' shelves.` Themoulds J have toothed racks, A', attached to their ends, teethdownvfardas shown in fig. 4, into the teeth of which the teeth of thecog-wheels mesh to draw the moulds uponvalnd from the shelf M. Thelteeth are eut away pmu, the middle part of the racks upon the upper andlower moulds, tor thepurposc `heremafterdescribed.` The racks A' havegrooves formed upon the outer side of their upper edges, to enable themto pass the pins, B', and upm,

the inner sides of their lower edges to receive the flanges formed uponthe ends of` the stationary 'shelf Maf` which keep them in their properrelative positions, and guide them while upon `andpassing `across saidshelf..A The racks A! also have hooks f0rmecl upon their ends, their-earhooksturning upwarhand the forward hooks turning downward, so that theforward hooks of each mould may in/terlock with the rear hooks ofthepreceding mould, and bodrawn forward by it until the teeth of the wheelsI can act upon the teeth of the racks of the following mould. The hooksand teeth of the racks A' are so formed that when the hooks areinterlocked as described, the teeth may be continuous and actas .onerack. C' are vertical racks, the upper ends of whichare securelyattached to the arches 7a', ot' the slides H, as shown in iigs. 3 and 4,and which move up and down upon the outside surface of the boxY F,whercthey are kept in proper position bythe guide-bars D', as shownin,fig. 3.. These racks, C', have teeth or notches formed in'the frontedges of their upper partsto receive the stopcatch E', and teeth ornotches formed in the rear edges of their lower parts 'For the cog ofthe wh'eels G- to take held of to raise or lowcrthe said racks and theirattachments.l The catches E' are securely attached to theopposite endsof tho shaft F', which passes through the machine from side to side, sothat the said catches may act simultaneously. The lower ends of thecatches are hold forward, forcing their upper ends back against theracks C', by the springs G', as shown in iig. 3. H' are arms' attachedto the catches E', and extending down so as to be reached and operatedto lift the said catchesl away from the yracks C', by the arms I',attached to the wheels G, in such positions that they will operate thearms I-I'and raise the stop-catches E' whenever the cog of the saidwheel G comes in contact with the teeth'of the racks C', to either raiseor lower them. J' are proigections formed upon the sides of the racksC', near their lower ends, the rear Vedges of which are made 'in ltheforni of a double inclined plane. K' is a lever, theupperend-oi` whichis pivoted to the side of the boX or frame F, and its free end isheldforward by the spring L', into a position to'be acted upon hythe'projection J', as the racks C' move up or down. M' is aconncotlng-rod, one end-of which is pivoted to the lever K', and theother end is piroted to the projecting end of the pin B', which passesin through and is pivoted to the sidcof-the box or frame F, as shown infig. 1. Whenever the projection J' comes in Acontact with `the endof thelever K', the pin B' is forced inward and forward, striking against apin permanentlyattached to the' racks of the upper and lower moulds, :isshown in fig. 4, and moving them forward so that the teeth of the wheelsI may come in` contact with the remaining teeth of said racks. Thisoccurs whether the machine is moving forward or backward. In the one'case the machine is moving in the same direction in which the mould ismoved, and the Wheels I carry it onward drawing the next mould into itsplace. But in the other ease the machine is moving in the oppositedirection from that in which the mould is moved, and the wheels Iimmediately carry it back into its former position. When the machine isat the pit the parts are in the positions shown in g. 3. The presser Sis then thrown back and secured by the spring-catch U'.l The hopper isthen lled with prepared clay, the presser S released, and the machinedrawn towards the drying door. rI'he first eii'ect is' to raise thevcatch E', and lower Vthe slides'G' g this fills the mould upon theshelf M, and lowers the shelves K L, so thatthe mould upon the lowestshelf, K, may interlock with the one upon the stationary shelf, M. .Thenext effect is to operate the pins B' and push. the full mould forward,so that the teeth of the wheels I may take hold vof therack teeth andpush the full mould upon the lowest shelf, L, and drawingthe empty mouldupon the shelf Mv. By this time the wheels have made an entirerevolution, and the racks, slides, and shelves, are again lowered,interlock-- ing the next empty mould upon the shelves K with the oneupon shelf M, and. unlocking the full mould'upon the lowest shelf, L,and lowering it so that the next shelt is ready to receive the next fullmould. Upon arriving at the drying door the moulds will all be filledand lowered infront of the doors N', ready to be takenout, except theone that remains upon the stationary shelf M. The moulds are then takenout, emptied, and placed upon the shelves in the rear end of themachine, in such a position that when the shelves are raised the mouldsmay passup without striking against the mould upon the shelf M.. Themachine'is then drawn back to the pit. This revolves the wheels in theopposite direction and raises the racks, slides, and shelves.4 As theshelves K pass above the plane of the stationary shelf` M, the rearedges of the empty moulds strike against the roller O', and are by itpushed forward so as to be in a postion to interlock with the one uponthe shelf M, as they descend, as before described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Operating the machinery for moulding brick from the drive orsupporting wheel, or wheels of the machine, subs-tantiallyin the mannerherein shown and described.` l

2.. The combination of the' slides H, racks C', cog-wheels G, and shaftD, with each other, substantially as' herein shown and described, forthe purpose of raising and lowering the shelves and moulds as set forth.3. The combination of the catches E', spring G', and arms H' I', witheach other, and with the racks C' and wheels G, substantially as hereinshown and described, and for the purpose set forth.

4. The combinationof the racks A', and cog-wheels I with each other, andwith the moulds .l and shaft D, substantially as herein shown anddescribed, and for the'purpose set forth.

5. The combination of the pins B', connecting-rods M', pivoted leversK', and springs L', with each other and with the projections J', of theracks C', substantially as herein shown and described, and for thepurpose set forth. v

The above specication of my invention signed by me this 13th day ofOctober, 1866.
